Plastic bag



The sole FIGURE is a front elevation of a plastic bag.

Horizontal bands of the claimed design are stippled to illustrate that these bands have a different appearance from the remainder of the bag body. Oblique shading lines are applied to non-stippled portions of the claimed design to illustrate that the non-stippled portions of the claimed design are transparent. The design is shown with symbolic breaks in its length. The appearance of any portion of the article between the breaks forms no part of the claimed design.

The broken lines define the bounds of the claimed design and form no part thereof. 

CLAIM The ornamental design for a plastic bag, as shown and described.
